Patent CA-2270647-C (CA)
Title: Remote control electronic display system
Inventor: GOTHARD DAVID
IPC: G09G3/28
Filed: 1999-04-30
Granted: 2010-01-26
Abstract: A remotely controlled electronic display sign which operates with a plasma display and which provides for humidity and heat control and the like allowing the sign to be used in various environments. The sign is essentially self-contained and includes those components necessary for enabling a display of desired material from a remote control source or one located at the sign. A controller in or associated with the sign is accessible either electrically, or through satellite transmission or other wireless transmission from the remote source which allows the display of the sign to be changed at will. Thus, an operator at a remote source may, with the aid of a pre-prepared graphic design, transmit that design to the controller at or associated with the sign for display of that graphic information and potentially with sound.

Title: Inflatable packer inflation verification system
Inventor: CORONADO MARTIN P
IPC: E21B47/09
Filed: 1998-11-25
Granted: 2005-02-08
Abstract: An inflation verification system for an inflatable tool includes at least an information collector associated with the inflatable element of the inflatable tool connected to a controller with a predetermined set of instructions for inciting communications with the surface. Communicators contemplated include atmospheric chambers which when opened create a negative pressure pulse which propagates to the surface.

Title: Indoor/outdoor electrical enclosure
Inventor: MENDOZA ANTHONY CERNAN
IPC: H02G3/12
Filed: 2001-06-05
Granted: 2011-03-29
Abstract: An outdoor enclosure for an electrical device includes a channel-shaped base plate, a five sided cover, and a flush-mountplate. The flush-mount plate has an opening that makes the front wall of the cover visible. The flush-mount plate allows the enclosure to be mounted flush indoors through a commercial building or a residential dwelling gypsum wall. The flush-mount plate has holes that are aligned with the threaded cylinders of the cover through which machine screws may pass to secure the cover to the flush-mount plate. The cover has no front flanges, and the bottom wall of the cover has slots, which allow the base plate to slide into the cover. The cover side flanges have holes and slots for side mounting. Additional side flanges that are bent from the top wall cover the upper parts of the side flanges of the cover, and prevent water from entering the enclosure from the top. A rear flange that is bent from the top wall prevents water from entering the top of the base plate. The cover top wall has a welded mounting plate for surface mounting. The channel-shaped base plate has holes at the bottom of its side flanges which are aligned with the holes of the cover side flanges. Machine screws pass through these holes and provide a way for securing the base plate and cover together. At the bottom of the base plate are slots for surface mounting.

Title: Vehicle transmission
Inventor: OBINATA JIRO
IPC: F16H3/083
Filed: 2001-08-31
Granted: 2005-02-22
Abstract: A transmission for a vehicle having a sub shaft supported in casings via bearings, and an input gear, an output gear, and a boss of a clutch outer, etc. stacked on the sub shaft and retained by a cotter key. The input gear and the output gear are helical gears, and thrust forces acting on the two gears are generated in opposite directions. A  rightward thrust force acting on the input gear is borne by the casing via an annular projection, the sub shaft and the bearing, and a leftward force acting on the output gear, which is separated from the cotter key by a gap, is borne by the casing via the bearing provided on the side face of the output gear. This arrangement eliminates any need for fixing gears supported on a shaft of a transmission by a nut or a bolt in the axial direction, thus saving space and reducing the number of parts.

Title: Multi-protocol wireless communication module
Inventor: REUL DAVID A
IPC: G08G1/123
Filed: 2001-09-12
Granted: 2009-06-30
Abstract: A wireless communication module communicates with a remote station and a plurality of motor vehicle control units that implement at least two different communication protocols within a single motor vehicle. The wireless communication module includes an RF interface, a processor and a selectable multiple protocol interface. The processor communicates with the RF interface and thereby communicates with the remote station. The processor executes translation routines and thereby provides requests to one of the plurality of motor vehicle control units. The selectable multiple protocol interface is coupled between the plurality of motor vehicle control units and the processor. The selectable multiple protocol interface converts processor requests into a format that is readable by the selected motor vehicle control unit and converts received diagnostic information into a format that is readable by the processor. If desired, both the selectable multiple protocol interface and the processor functionality can be incorporated within the FPGA.

Title: Torque assist method and apparatus for reducing photoreceptor belt slippage in a printing machine
Inventor: ADILETTA MARK A
IPC: G03G21/00

Granted: 2004-09-28
Abstract: A belt drive module and a corresponding method includes or employs a belt that moves along a path, at least one support roller or other structure that supports the belt as it moves along the path, a drive roller that effects movement of the belt along the path, a tension roller that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the belt, and a torque assist drive that applies a torque assist force T d at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller, e.g., a stripper roller of an electrophotographic imaging system. Advantageously, the torque assist force T d facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processing stations) by reducing slippage between the drive roller and the belt that may be encountered due to belt wear, toner contamination and/or other debris.
